Abstract: An electronic controller for controlling a trolley pole switch is disclosed.   The trolley pole switch switches the path of travel that an energy collector of a trolley pole takes through the  trolley  pole  switch  at  a junction of  power conduits diverging from the trolley pole switch.  The electronic trolley pole switch controller includes a signal processing device and a power controlling device employed in tandem to control the frog solenoids of a trolley pole switch.  The signal processing device detects and processes a plurality of modulated signals.          Each modulated signal represents a request to switch the path of travel that the energy collector takes through the trolley pole switch to a desired one of the power conduits diverging therefrom.  In response to each modulated signal, the signal processing device generates an intermediate command signal indicative of a command to supply power to the appropriate frog solenoid that effects the switch in the path of travel through the trolley pole switch to the desired power conduit.   The power controlling device receives the intermediate command signal  from the  signal processing device  and in response thereto  supplies  power  to  that  frog  solenoid.   The  frog solenoid energizes and therethrough compels the trolley pole switch to switch the path of travel that the energy collector will take through the trolley pole switch to the desired power conduit.

Abstract: A processor is provided with a first set of digital information that includes a first, resolution-independent structured representation of a document.  This first representation is one from which various image collections (e.g., sets of page images) can be obtained, each such image in each such collection having a characteristic resolution. From the first set of digital information, the processor produces a second set of digital information that includes a second, resolution-dependent structured representation of the document.  The second structured representation is a lossless representation of a particular one of the image collections obtainable from the first structured representation, and it includes a set of tokens and a set of positions. The second set of digital information is produced by extracting the tokens from the first structured representation, and by determining the positions from the first structured representation. Each extracted token includes pixel data representing a subimage of the particular image collection. Each position is a position of a token subimage in the particular image collection. At least one of the token subimages contains multiple pixels and occurs at more than one position in the image collection. The second set of digital information thus produced can be made available for further use (e.g., distribution, transmission, storage, subsequent reconversion into page images). Applications of the invention include high-speed printing and Internet (World Wide Web) document display.

Title: Method and apparatus for determining a profile of an image displaced a distance from a platen

Abstract: A profile detector in a scanning system measures spacing of an original non-planar image from a reference image plane of the scanning system. The spacing is measured by projecting a spot of light, with a collimated light source, onto a scan line of the original non-planar image at an angle that is oblique with respect to the fast scan direction of the scanning system. A first photosensor converts optical information reflecting off of the original non-planar image at a first slow scan position into electrical profile data. A position along the fast scan direction is identified for the first slow scan position by locating the spot of light in the electrical profile data. The located position is compared with a pre-recorded position along the fast scan direction for the first slow scan position. The pre-recorded position defines a position where the first photosensor would have detected the spot of light if it reflected off of a planar image. The difference between the located position and the pre-recorded position is used to determine the value for the spacing between the original non-planar image and the reference image plane at the first slow scan position. In a one pass scanning system, a second photosensor records image data at a second slow scan position that is offset from the first slow scan position. The offset provides sufficient time for the scanning system to calculate the spacing of the original non-planar image from the reference image plane before the second photosensor records image data at the first slow scan position. In a two-pass scanning system, the first photosensor records the image data during the second pass. The scanning system compensates for image distortion caused by the calculated spacing by either adjusting system scan parameters or by performing image processing techniques.

Abstract: Disclosed is a uniquely designed sled and a method for its  use in  distributing  roof  netting  on  a  building  during construction and prior to installation of the roof itself.  The sled is brought to the roof  level  so that  it straddles the secondary roof members of the building under construction, and is then loaded with a roll of roof netting.  A rope attached to the front of the sled allows it to be pulled across (perpendicular to) the roof support members as the netting is unrolled and deployed through a distribution box.  The rails of the sled are long enough to stretch across at least two (2) secondary roof members at a time in order to prevent the sled from falling through as it slides across  them.    A  specially  designed  mounting  platform  and distribution box with a top door are provided in the sled to efficiently dispense the netting onto and over the secondary roof members.   The outside edges of the netting are attached to the sides of the building, and the inside edges are attached to each other to create a single large net covering the entire roof area.

Granted: 2004-05-04
Abstract: A bird deterring device for protection of a reservoir or other body of water is disclosed. The deterring device provides an array of wires stretched across the reservoir, wherein adjacent wires are oriented in a parallel manner and are spaced apart by approximately 12 feet. Each wire is supported at a first end by an anchor rod driven into the ground of the shoreline defining the reservoir or body of water. Each wire is supported at a second end by an adjustment rod carrying a wire tightening mechanism which allows the wire to be tightened until taut. The wires reduce or eliminate use of the body of water by water birds by providing both visual and auditory deterrents. Wind, moving about the wires, creates a high-pitched whine that tends to annoy and repel birds. Additionally, birds tend to reject making a water landing due to the location of the wires, preferring instead to divert to other bodies of water.

Abstract: A tool for driving a nail or other fastener is actuated by a caseless propellant charge (62) formed of combustible material that is transported in to a combustion chamber (44) on a strip (64). The propellant charge (62) is ignited by striking a sensitizer portion (90) of the charge at an oblique angle. The ignition member (66) intermixes the sensitizer material (90) with an oxidizer layer (88) of the surface of the propellant charge (62), resulti ng in combustion of the charge. When ignited, the propellant charge (62) is compressingly interposed between an orifice plate (74) and a movable portion (80) of the combustion chamber. The orifice plate (74) includes a pedestal (78) with an annular compression surface that separates the surface of the ignition area from the remaining surfaces of the charge (62); insuring that ignition gases are forced through the charge (62). An annular C-shaped ring (82) is interposed between the orifice plate (74) and the movable portion (8 0) of the combustion chamber (44). When the charge (62) is ignited, the resulti ng gas pressure resiliently expands the annular C-shaped ring (82) and urges opposite axial ends of the C-shaped ring (82) into sealing relationship between the relatively movable components of the combustion chamber. Combustion gases are communicatedthrough orifices (76) in the orifice plate (74) to a cylinder (40) where the gases force movement of a driver (42), whi ch driver strikes and drives a fastener such a nail. The driver (42) is reciprocally movable within the cylinder (40) and is returned to its precombustion position by a gas spring return cylinder (17). The gas return cylinder (17) is mechanically interconnected to the driver (42) and contains a sealed gaseous fluid that is independent of and segregated from fluids in th e combustion chamber (44). An assembly (60) for deaccelerating the driver includes a series of spaced and aligned progressively sized metal cup member s (110, 112, 114) of progressively increasing mass, contact surface area and interface angles.

Abstract: A gerotor pump is described for use with non-compressible fluids such as automotive coolant or hydraulic oil. The pump includes three separate pump outlet ports, a bypass return passage, and an integral four position spool valve. Increasing back pressure from a downstream load is sensed by the spool valve which moves accordingly to restrict the fluid supplied. In the first position a full flow fluid is supplied to the load from all three ports. In the second position one port is vented to the bypass and the flow from the other two ports is directed to the load. In the third position two ports vent to bypass, and one port drives the load. In the fourth position all ports vent to bypass. In each case flow vented to bypass is not first compressed, permitting a smaller motor to be used.

Granted: 2004-03-23
Abstract: Methods and systems for calibrating transceivers are described. Analog transceiver components create errors, such as gain and offset errors in a receiver or a transmitter portion, which are compensated by adjusting digital signal processing in the computing portion of the transceiver. Errors can be measured in a calibration procedure and determine d compensating values stored in a memory device of the transceiver. These values can then be retrieved when the transceiver is initialized for usage during signal processing of signals received by and transmitted by the transceiver.
